Patented 21,1933 v I WALDEMAR A..EN15TER, or LONG BEACH, omronnm noonnocx Application flldd September 13, 1980. Serial No. 481,707.

This invention relates to a door lock-for the doors of houses, automobiles, and the like, and the prime object of my invention -is toprovide a lock which will hold the door tightly againstthestop at all times,

and, thereby prevent rattling. of the door.

Another object is to provide a locking bolt of the character stated which can be applied to many well-known types of locks now in use. i I

A further object is to provide a lock which is simple in construction and effective in use.

Furtheradvantages of my invention reside in the fact that the door stop need not be set accurately relative to the door, but the dodr will be held tightly against 'it irrespective of slight errors in construction.

My lock 4 is mounted in the door. 1 and includes a metal sheath or casing 5 which fits into a suitable bore or other recess in the 1 door. A multi-headed locking bolt 6 is ro- 9 tatably mountedin the door 1 adjacent the outer swinging edge thereof. This bolt is preferably formed with four teeth or heads, and its function is to hold the door tightl against the stop, as will be further described? locking bolt cannot .slip thereon. quently once the door is held against the outer end of this dog is tapered, as shown at 10, and engages one of the teeth or heads of the locking bolt 6, as shown in Figure 1.

A strike plate 11 is mounted in the jamb 2 and preferably provided with a central wall 12 against which one of the teeth of the locking bolt bears to hold the door tightly against the j ambr As shown in Figure 1, the

tip of one ofthe teeth of the locking bolt rests against the tapered surface 10 and consequently the sliding dog 8 can be moved outwardly, thus tending to further rotate the locking bolt 6, and will therefore hold the door tightly against the stop 3. The tapered face 10 is not so abrupt but that the Conse stop, it will be held there until the door is 'f urge the fin outwardly and rotate the lock- Also In looking bolt will operate with opened.

The locking bolt does not move horizontally,

but merely rotates on its axis 7, which axis is mounted in the metal sheath.

- A sliding dog 8 is provided with long guides 9-9 so that it will move'back-and forth horizontally without binding. The

' Havifig described'my invention, I claim:

' engaging the strike plate, a wedge-s a ed heads, said dog'having a tapered face cooperating with one of the heads for imposing a dog slidably mounted in the door, said ast named dog engaging another of the heads of the locking bolt, and spring means engaging the sliding dog whereby said sliding dog is yieldably pressed towards the locking bolt, thereby tending to rotate said locking bolt and to hold the door against the stop, means to retract said sliding dog, a wall in said strike plate against which one of the heads of the locking ,bolt bears, a fin pivotally mounted to said wall, and spring means urging said fin outwardly.

2. In a latch construction, a rotary bolt capable of free rotation in all positions when released, including a plurality of heads, any one of which is adapted to en-' gage a keeper, means engageable with any one of the heads, said means including means for imposing a continuous rotation of the bolt in a latching direction when the bolt is in keeper engaging position.

3. In a latch construction, a casing, atrotary bolt mounted in the casing, said bolt being capable of free rotation in all positions when released, including a plurality of heads any one of which is adapted to engage a keeper, a movable dog arranged in the casing and engageable with any one of the continued rotation of the bolt in a latching direction when the bolt is in keeper engaging position.

4. In a latch construction, a casing, a rotary bolt mounted therein, said bolt being capable of free rotation in all positions when released, and including a plurality of heads any one of which is adapted to engage a keeper, a sliding spring projected dog arranged in the casing, guide means for thedog, said dog being engageable with any one of the heads, the dog having a tapered face cooperating with one of the heads for imposing a continued rotation of the bolt in a latching direction when the bolt is in keeper engaging position, and means for retracting 'means -forimpos1ng acontinued rotation o the boltin a latching direction when one of the heads is in keeper engaging position. 3

6. In a latch construction, a rotary bolt capable of free rotation in all positions when re eased, including a plurality of heads, any

one of which is adapted to engage a keeper, a

sliding dog adapted to engage suecesslve heads of the bolt in non-latching position,

means for normally projecting the dog whereby upon rotation of the bolt in a latching direction said dog is automatically retracted by one of the successive heads, andsaid successive head to impose a continued;

rotation of the bolt in a latchin direction. 7
